Latas Patent No. 77,639, dated May 5, 186s.

Iurnovrn sinn-HILL PLoUen.

TO ALL WHOM ITMAY CONCERN: l

Be it known that I, DAVID A. MAnUnL,of Napa City, county of Napa, -State of California, have invented an Improved Reversible Side-Hill Plough; 'and I do hereby declare the following description and accompanying drawings are sutlicient to enable any person skilledin the art or science to which it most nearly appertains to malte and use my said invention or improvements without further in'vcntion or experiment. i

The nature of my invention is to provide a reversible side-hill plough, so constructed. that the mould-board is divided above the point, andthe two parts pivoted tothe front and rear of the standards and frame, soV that, by turning-from right to left or left to right, a perfect plough is formed without alteration to the beam.

To more fully illustrate and explain my invention, reference is had to the accompanying drawings, forming a part of this specification, of which-l Figure 1 is a top view',

Figure 2 is a bottom view, and

Figure 3 is a side elevation,

Similar letters of reference in each of the guresindieate like parts. a

A represents the land-side of my plough, made considerably longer than that of the ordinary plough, and is tapering from the centre to theA heel. Thooppositecn'd o r point is bevelled ilatw'ise at the top, and is made wider than at the heel, for the purpose of keeping the plough to the land; A lng or projection, B, is made at the extreme end of thepoint, so that as the plough-point is ychanged from right to left, it will lock against it, and form a close and smooth'bevelled joint, the rear part of the faces of the points being cut away, and the ond of the land-side chamfered for that purpose, A

A broad standard, C, is placed back of the point of the land-side, at the top 'of which is attached a dat bar, 'D, bent downward to vnear the heel of the land-side, where it is held by a post, E.

The plough-point and share F, when removed from the mould-bo'ardfis,nearly triangular inform, and has two cutting-points, G and G', and is hinged to the standard by a pivot,vH, passing through it, and an arm, I,`into the land-side, which allows it to swing to the right or left about ono-quarter of a circle, atwhich point it is locked against the land-side.

The mould-board J is riveted tothe long arm T, which is hinged to the post E at the rea-r end of the landside, and, when brought in position against the shire, forms la perfect plough, the two parts coming in eoutaet, where it is held by hooks or lugs, at the end of rod's L L, which slide up and down back'o'f the mould-boards into holes L L at the sideof the point or share. 'I he rods cross each other diagonally above the arm K, and are bent at right angles for convenient handles for the driver. v p v l The handles may be attached to the broad standard, and be out of the way of the swinging mould-board.

The beam maybe attached to the at har.

In operating with my plough, at the end 'of the furrow, the rod which holds-thc two parts together is drawn up, and the point turned to its place at the opposite angle by its hold in thesoil, when the mould-hoard is caused to swing around on its axis by the driver, to the point or share,'where its locked and prepared for turning another furrow. Y I p Having thus described my invention, what I claim, and desire to secure byfLe'tters Patent, is

1. Dividing the'plough, betweonthe share and 'mould-hoard F and J, and hinging the two parts to the land-side and standards, so that bys-wingin'g them tc the right or left, and joining the two said parts, they will form a perfect plough, substantially as described.

2. Construction ofthe land-side A, wider in front-than at the heel, so that the line of draught will incline towards the land, substantially asdescribed,

vIn witness whereof, I have hereunto set my hand and seal.
